Previously,
LegacyHiveTableScanonly supports hive partition columns of string type, this patch leverage theBinderto augment the expressions (literals) with their corresponding types information and feed it toExpressionToPartitionFilterString, thus has the power to handle different partition column types such asTimestampandDate.After this patch, iceberg can support reading partitioned tables in our existing hive metastore which has
dateandtimestamptyped partition columns.
